KNIFE HOOK ADJUSTING SLEEVE Filed May 26, 1931 Inventor lfatented Dec. 27, 1932 PATENT OFFICE RICHARD P. BARNES, OF SPINDALE, N ORTH CAROLINA KNIFE HOOK ADJUSTING SLEEVE Application filed May 26,

This invention relates to a` knife hook adjusting sleeve which can be applied on all looms equipped with dobby heads, and all rods and swivels that work in a similar manner, the general object of the invention being to provide means for taking up wear without removing any parts so as to save wear of all dobby head parts and to save time and labor,

land aid production and secure a better grade of cloth.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed outin the appended claim.

/ In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is an elevation of a knife hook swivel and pin showing the invention in use.

Fig. 2 is a view taken in `quarter turn of v Fig. 3 is a sectional view through the parts shown in Figs. l and 2.

Fig. l is an end view of the sleeve.

In these views, the numeral l indicates the knife hook and 2 the pin which pivots the member l to the rod 3. The improved sleeve is shown at 4 and nuts 5 are placed on a threaded part of the rod 3 to hold the sleeve in position and by tightening these nuts the sleeve can be adjusted to take up wear.

The sleeve is provided with the extensions 6 which have concave edges 7, to contact the convex ends 8 of the prong end of the meniber l and these parts 6 are provided with the 4o recesses 9 on their outer faces. These recesses are for oiling purposes and by placing lubricant these recesses will aid greatly to the life of the sleeve and the parts that come in contact therewith.

From the foregoing it will be seen that it is simply necessary to tighten the nuts 5 to move the sleeve 4 in a manner to take up wear between the parts so that it is not necessary to remove any parts in order to adjust 5o them.

1931. Serial No. 540,179.

As is well known, the knife hook, swivel and pin of a dobby head loom is subject to a lot of waste and to give good results it has to be set so that here will be no lost motion except to work sidewise.

rIhis sleeve will more than double the life 'of the knife hook swivel and pin as it takes all the wear off the knife hook and pin and the loom will also give better results as it takes a lot of the vibration out of other parts of the dobby head.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts,

`provided that such changes fall within the scope of the appended claims.

Having thus described my invention, what I claim as new is In combination with a forked member having the ends of its prongs rounded and a rod having an eye with the pin passing through the prongs and said eye, a sleeve slida'bly arranged on the rod and having a forked end, the ends of the prongs of which are formed with rounded recesses to receive the rounded ends of the prongs of the iirst member, the bore of the sleeve, at the forked ends flaring to receive a part of the eye and nuts threaded on the rod and engaging the sleeve for adjusting the sleeve to take up wear and the outer faces of the ends of the prongs of the sleeve having lubricant receiving recesses therein.

In testimony whereof I affix my signature.

RICHARD P. BARNES.
